摘要
随着我国高速铁路的飞速发展,风区运营的高速铁路不断出现,需对高速列车的抗横风倾覆性能进行深入研究。在对比分析日本的国枝方法和日比野有方法的基础上,针对我国CRH5H型动车组建立了横风倾覆静态计算模型,并对车体自重、转向架一系及二系悬挂刚度对列车抗倾覆性能的影响进行了数值模拟。数值计算结果符合实际规律,计算模型和方法可为风区运营车辆抗倾覆安全设计提供参考。
With the rapid development, more high-speed railways are constructed in strong wind regions, so the o- verturning resistance of railway vehicles against crosswind should be studied. Two different methods, KUNIEDA＇s method and Yu HIBINO＇s method are compared, which are used to evaluate the overturning stability of railway vehi- cles. An overturning resistance model is established based on the CRHSH EMU, the effect of different parameters, such as dead weight, bogie frame I and the hanging stiff- ness of bogie frame II against overturning is studied. The calculation results are in accordance with the order of na- ture. The numerical model and method can be used in the safety design of railway vehicle running in strong wind re- gions.
